Igneous, Sedimentary, and Metamorphic
A igneous rock is formed by by magma cools and solidifies and hardens. A sedimentary rock is formed by a sediment that is deposited over time usually formed in oceans and lakes and in some sort of water. metamorphic changes over time by heat and pressure.
This is a metamorphic rock it can be formed from heat and pressure it sounds like a hot rock so i do not want to touch it might burn me but if was cooled it won't be hot so then you can touch it.
This is a sedimentary rock it is formed by deposited over time usually as layers of the bottom of the lake and oceans sounds like a smith rock right.
This is a igneous rock it is formed when magma is cooled and solidifies, it may do this above or below the earth surface. I think it is bumpy and rough there must be some strong metals are down there with it.
